Just to mention it: Mark's own Maplet (available on this very site <g>) bakes .B3D lightmaps.
Also I've used LightMapMaker from WindSoft (now AwingSoft) with decent results. I paid the ~$30 fee when it was charged for, but then they released that full version for free. It's available at:

Its baked lightmaps can be used with Blitz3D (I did some tests with 'em).
